An air conditioner includes a heat-exchanger positioned in an outdoor unit and configured to conduct heat-exchange between air provided from outside of the outdoor unit and a refrigerant. The air conditioner also includes a fan configured to generate a flow of the air that is from the heat-exchanger to an outlet of the outdoor unit. The air conditioner further includes a driving unit configured to provide a driving force to the fan. In addition, the air conditioner includes a first member positioned in the flow of the air generated by the fan and a second member configured to guide a flow of the air to reduce collision between the air and the first member when the fan is operated.
Abstract:
A gigabit passive optical network (GPON) system for fiber to the home (FTTH) service must provide a downstream data rate of an optical band to provide IPTV service with hundreds of channels to subscribers, and must be able to provide an upstream data rate of an optical band using a currently available BM-IC chip. A currently available BM-IC chip for a GPON has 1.244Gbps and 2.488Gbps modes. Accordingly, an optical network terminal (ONT) for a GPON that is capable of providing a downstream transmission band of 10-Gbps and an upstream transmission band of 1.244Gbps or 2.488Gbps, and a method for processing an upstream frame in the terminal, are provided. The GPON ONT can provide 20Mbps, high-definition IPTV service with 500 channels and can provide both upstream data rates of 1.244Gbps and 2.488Gbps according to a user's selection without using an additional device.
Abstract:
The present invention relates to a medical adhesive tape dispenser in which a medical adhesive tape is covered up by a case when not in use and carried by a user, and cut in a simple way upon being extracted for use. The medical adhesive tape dispenser of the present invention includes a case body (1), a cutter blade (2), a cutter blade protection cover (3), a return spring (4), and an extraction port cover (5). The case body (1) has a cylindrical shape with a closed exterior and an interior with a reel (111) on which is mounted a tape roll (100). The case body (1) has a front surface wherein an exposure hole (121) and a tape extraction port (122) communicate with each other in the vertical direction. The exposure hole (121) has an interior provided with a cutter blade mounting rib (123). The cutter blade (2) is mounted on the cutter blade mounting rib (123) of the case body (1). The cutter blade protection cover (3) is arranged above the cutter blade (2) to selectively open/close the exposure hole (121). The return spring (4) is supported beneath the cutter blade protection cover (3) and at the interior of the case body (1) so as to selectively allow the cutter blade protection cover (3) to rotate about an axis. The extraction port cover (5) is joined to both sides of the case body (1) such that the extraction port cover is rotatable via a hinge shaft (53), enabling the selective opening/closing of the exposure hole (121) and of the tape extraction port (122).
Abstract:
The present invention relates to a plasma display apparatus. The plasma display apparatus includes a first layer and a second layer over an upper substrate of a plasma display panel. The first layer emits light having a peak at a first wavelength region with light emitted from a discharge space. The second layer emits light having a peak at a second wavelength region lower than the first wavelength region with light emitted from a discharge space. The first layer and the second layer are disposed over a dielectric layer of the upper substrate. The plurality of scan electrodes are divided into first and second groups and then supplied with scan signals, cycles of scan signals supplied in first and second subfields of a plurality of subfields constituting one frame are identical to each other, and scan bias voltages supplied to the first and second groups in at least any one period of an address period are different from each other.
Abstract:
A plasma display apparatus includes a plasma display panel (PDP) including a front panel with a plurality of scan electrodes and sustain electrodes formed thereon and a rear panel with a plurality of address electrodes formed thereon and a driving circuit that applies drive signals to the scan, sustain and address electrodes so that driving can be performed by time-division of one frame of an image displayed on the PDP into a plurality of sub-fields. Each sub-field includes reset, address, and sustain periods, and a first signal that gradually falls is applied to the scan electrodes during the address period. In the plasma display apparatus, after a rising signal and a falling signal are applied to the scan electrodes, the first signal is applied before or after the scan signal is applied during the address period, thereby preventing a loss of wall charges and performing stable address discharges and sustain discharges.
